The upper side of the'bese ring 24; is formed with :L plurality of lugs 28, similan to thelugs 23, zmd'upen h'ese ugs 28 an intermediate rng 29 is supported. Thisring 29 is smla o the ring Q4? but is of smanetdialmfeiiel'.4 B isformed with recesses 30, which seat en the lugs' eS indicated. Upon thisin'ermedee ring 29 hree mere simler intermediate rings 31 are piled insuceessien9 seid rings 31 being e greualfv decreasing diazfnetey in, anupward deciol. These rings 3l are provied on their lippe? Sices lwithkings 32 which are received in Cerrespending notches 33 en the underside of he rings next ahime.v En ths- Way when ik@ emnplete emmerdeformed it presente e pluof the burner. On the uppermost of thsese rings3l, a crown 35 seats. said crown being.

in the form of a small thick dislr having notches 36 on its under side,which seat ou the upwardly projecting lugs of the ring just below. Onthe upper side ot' the crown, 235. radial grooves 37 are formed.

Passing centrally up through the burner l provide a feed pipe 38, andthis feed pipe hasa serrated edge 39, which is disposed a short distancebeyond the crown 35. The

' upper end of 4the pipe 38 is threaded so as to receive a clamping nut110 which seats on the upper side of the crown as shown. The bottom 22of the base is provided with a downwardly otiiset, integral cross bar orcross head 41 and the feed tube preferably passes through `this crosshead as shown. On the tube 38 a nut l12 is provided'which seatsagainstthe under side of this cross bar.

' From this arrangement it will be seen that bolts passing through thehead 3, as 'shown in Fig. 1. The lower end of the feed tube, 38 connectsby a suitable elbow la with a horirental supply pipe Centrally .disposedunder the burner on the floor Ll-G l provide a basin dr pan 47 having aslightly dished cover 48 with a central opening 49, and this cover isadapted to catch any of the Jfuel which drips down unconsumed from theburner. Ata suitable teint under the base '19 of the burnerl provide agas burner :70,

which operates as a pilot burner. This burner should be lighted beforethe liquid 'fuel burner and operates to heat the rings so Athat theywill Vaporize the liquid fuel, and .it will set fire to the vaporspassing up- .wardly.

l Acreasing 1n 'diameter toward the upper cud l lnthe operation of theburner, the liquid 'feed i e 38 and flows downward] through the groovesoi the crown, it then descends in succession into the annular cups whichare formed in the intermediate rings. In this connection attention iscalled to the fact that the edge of each intermediate ring is disposedover the cup next below of the oil or liquidfuel should. n1 oibeconsumed by the timeit reaches the cup of the base ring, it willoverflowonto the'bottom 22 of the base 18 and fall through the central opening21 onto the cover 18 of the pau 47. Special attention 'is called to thetact thatall of the intermediate rings and the base ofthe burner haveannular air vents supplying them respectively with a sufficient quantityof air.

By removing the burner .from the furnace and removing the nut 40, thecrown and the rings may be removed and cleaned.

Having describedv my yinvention ,'whatl claim as new and desire tosecure by Letters Patent is: l l v A burnerhaving `a dished base'with acentral opening, bar transverse said opening, a fuel pipe passingupwardly through said bar and secured thereto, a plurality of burnerrings piled vone upon another and progressively of smaller diameter inan upward direction, said rings having projecting lugs therebetweenforming air spaces between the adjacent faces of said rings, the upperend of said fuel pipe having a thread, a nut received on said thread,and a crown in the form of a. disk under said nut and clamping all ofsaid rings to said base, said rings having annular grooves in the upperfaces thereof adapted to hold f1 liquid t'uel.'

ln witness-that I claim the foregoing I have hereunto subscribed my namethis 28th day4 of January, 1910.
